Brief Introduction
The NVIDIA/Mellanox InfiniBand MCP7Y40-N001 is an 2x 400Gb/s twin-port OSFP to four 200Gb/s twin-port QSFP112 Direct Attached Copper cable. The 8-channel twin-port OSFP end uses a finned top form-factor for use in Quantum-2 and Spectrum-4 switch cages. The four 200G ends support 2-channels of 100G-PAM4 (200G) and use a flat top QSFP112 for use in ConnectX-7 adapters and BlueField-3 DPUs using ridiing heat sinks on the connector cage. This cable is compliant with OSFP MSA, QSFP112 MSA (Multi-Source Agreement) and IEEE 802.3ck standards.
DACs offer the lowest latency, so are widely used in data centers to connect servers and GPU compute systems to the top-of-rack (TOR) switches and link spine-to-super-spine switches inside racks over short cable lengths. DACs are also used to create InfiniBand storage fabrics with hard-disk-drive (HDD) and flash memory subsystems.
Featuring a simple design and minimal components, DAC cables offer the lowest-cost, lowest-latency, and near-zero-power connections for high-speed links. They enhance port bandwidth, density, configurability, and reduce power requirements in supercomputers and hyperscale systems.

 | Optical transceivers port(LC) For LC port, there are two types of single-fiber bidirectional optical transceivers (one LC connector) and dual-fiber unidirectional optical transceiver (two LC connectors). Single fiber bidirectional is used to send and receive signals in one fiber, and dual fiber unidirectional optical transceivers are used to one fiber to send signals and other fiber to receive signals. |
